1. What is a surge test?

Professional explanation: It is to conduct a simulated lightning strike test with a specified waveform, a specified amplitude and a number of electrical and electronic products to understand the product's surge protection threshold.

For example, it is to test electronic products to see if they can withstand lightning strikes.

 

2. Why add an external lightning protection device?

Whether an electronic product can withstand the surge shock test, in addition to the surge protection capability at the beginning of the electronic product design, it is also necessary to consider the safety when encountering a larger surge shock. This is the most prominent performance in the LED street light switching power supply. Many LED street light switching power supplies have their own 3kV or even 6kV surge protection design. However, they still cannot meet the needs of protection and safety in practical applications, and external lightning arresters need to be added.

 

3. The lightning arrester is broken, and the equipment is not broken?

In the actual surge test, there are many LED street light switching power supplies installed with external lightning protection devices, but the phenomenon of "the lightning protection device is not broken, but the power supply is broken" still occurs. The reason is that although these lightning arresters work when the surge occurs, the protected power supply is damaged due to excessive residual voltage.

 

 

 

 

TP20D Surge Protection Devices(SPD)

The lightning arrester adopts UVT technology, and has the functions of leakage current and freewheeling interruption, working status indication and power-off function. The maximum protection lightning current of the product is 20kA, and it can withstand the surge voltage of 20kV.
